Isolation and identification of secondary metabolites from medicinal plants could be tedious and time consuming. Therefore, any technique that could be used to confirm the identity of medicinal plant constituents without isolating them will save time and resources. Chlorophora similar to many genera in the Moraceae family have been demonstrated to be rich sources of polyphenolic compounds with important biological activities. The current study was designed to employ HRESI-MSn analyses to qualitatively examine isolated polyphenolic compounds from the stem bark of Chlorophora regia. Based on the HRESI-MSn data obtained, the fragmentation patterns of the compounds under study will be proposed and could be used in their identification in a matrix. Five polyphenolic compounds were successfully isolated and purified using various chromatographic techniques including column chromatography, thin-layer chromatography (TLC) and preparative HPLC. The structures of the isolated compounds were elucidated by in-depth analyses of their 1D and 2D NMR and mass spectroscopic data. HRESI-MS/MS was further used to characterize the isolated compounds. Five polyphenolic compounds including three Diels-Alder type adducts: sanggenon C, kuwanol E and chalcomoracin; two stilbene derivatives: chlorophorin and isochlorophorin were isolated from the stem bark. The tandem MS fragmentation patterns of the compounds in positive mode, were successfully proposed. The fragments obtained and proposed fragmentation patterns of the isolated compounds could be employed qualitatively in the identification of the studied polyphenolic compounds in a matrix.

The issue of water quality is becoming ever more serious as freshwater resources are severely degraded across the world. Water quality in rivers, streams, lakes, and subterranean aquifers is deteriorating, posing a threat to human life and ecological sustainability. A proper study of the physico-chemical properties of the water samples give us insight into the quality of life in a specific region, as poor water quality not only affects the aquatic life but the surrounding ecosystem as well. In the present study, 30 different water samples were collected from different regions of district Mardan and they were analyzed for their physico-chemical properties such as pH, total suspended solids, conductivity, total dissolved solids, nitrates concentration, sulphates concentration, chlorides concentration, dissolved oxygen, and biochemical oxygen demand. The results of the analysis show that most of the parameters have significantly higher values than the WHO permissible limits. From the analysis of water samples, the researchers have been able to designate the study area with poor water quality and to propose future advice for sustaining the water quality in the region.

Changing learning patterns from senior high school student to college student status is difficult, and each individual's response varies, some of which cause stress. Factors that cause stress are internal and external, and external factors consist of physical, conflict, emotional, and behavioral conditions. In comparison, the external factors consist of the physical environment, work environment, community environment, family environment, economic and legal problems. The burden of life stress is heavy and impacts the physical, such as feeling dizzy, nauseous, ulcers, and difficulty sleeping. Sometimes causes a person to take self-medication to overcome these uncomfortable symptoms. This study aims to determine the characteristics of early-level students and the stress level of early-level students at one of the State Universities of East Kalimantan Province. This study used a qualitative descriptive design on 121 students. Using a questionnaire through a cross-sectional approach with a purposive sampling technique. The results showed that the stress level of students showed mild stress as much as 30.58%, moderate stress at 56.20%, and severe stress as much as 13.22%. The number of students who did self-medication was more than those who did not provide treatment for the symptoms, 79.34%.

The purpose of this research is to separate gadolinium(III) from terbium(III), by the liquid-liquid extraction method, with the extractant dibutyl dithiophosphate. Gadolinium(III) and terbium(III) have been selected in this study to see if the two metallic ions still could be separated although they have only one difference in atomic number, and in fact, terbium (65Tb) is the next to gadolinium(64Gd), in the lanthanide series. Also besides, the two metals have been found together in the same mineral such as gadolinite, and in some other minerals in Indonesia. Extraction parameters have been firstly selected and extraction conditions have been optimized as well, using the experimental design of Plackett Burman. Thus, experiments have been done to select which of the nine parameters (i.e. Gd(III) and Tb(III) concentrations, the concentration of the extractant (dibutyl dithiophosphate), pH, volume ratio of aqueous phase to the organic phase, extraction temperature, shaking rate, shaking time, resting time (after shaking), have their significant effect on the extraction efficiency and separation. The data resulted from this study show that there were five of the nine factors studied that determine the extraction efficiency and separation. They were (with its respective optimum value in the bracket): Gadolinium concentration [Gd(III)](5 ppm), terbium concentration [Tb(III)](5 ppm), pH(3.0), shaking time (10 minutes), and rest time after shaking (10 minutes).

The increase incidence of fungal infections, the resistance of fungal strains to existing drugs and the toxicity assimilated to long term usage of antifungal drugs as prompted the search of new alternative from natural source. In this study we have evaluated the antifungal properties of the essential oil of the rhizome of Z. officinale, a plant known for its various biological properties and used in food industry as spice. An antifungal ointment with Z. officinale essential oil as active principle was also formulated and its antifungal properties evaluated. GC/MS analysis identified Zingiberene (22.36%), 1.8-cineole (15.54%), geranial (11.91%), camphene (11.09%) and geraniol (8.75%) as the main constituents of Z. officinale essential oil obtained by hydrodistillation. The oil showed a significant antifungal activity against clinical isolate of Candida krusei with MIC 800 ppm by microdilution method. The formulated ointment containing 10 % glycerol, 60 % vaseline, 8 % hydrosol, 20% lanolin and 2% Zingiber officinale essential oil (Formule E1) was found to follow pharmaceutical standards according to European Pharmacopeia and also showed good antifungal properties
